The European Union (EU) has 24 official languages, of which three – English, French and German – have the higher status of "procedural" languages of the European Commission. Irish previously had the lower status of "treaty language" before being upgraded to an official and working language in 2007. However, a temporary derogation was enforced until 1 January 2022. The three procedural languages are those used in the day-to-day workings of the institutions of the EU. The designation of Irish as a "treaty language" meant that only the treaties of the European Union were translated into Irish, whereas Legal Acts of the European Union adopted under the treaties did not have to be. Luxembourgish and Turkish, which have official status in Luxembourg and Cyprus, respectively, are the only two official languages of EU member states that are not official languages of the EU. In 2023, the Spanish government requested that its co-official languages Catalan, Basque, and Galician be added to the official languages of the EU.

English is a West Germanic language in the Indo-European language family, whose speakers, called Anglophones, originated in early medieval England. The namesake of the language is the Angles, one of the ancient Germanic peoples that migrated to the island of Great Britain.
